The joint interactions of hydrodynamics, radiative transfer and photochemistry destabilize a hydrodynamic system that would otherwise stable. This observation is of important interest in itself. In this paper, the stability of baroclinic, axially symmetric vortex on an f-plane to axially symmetric disturbances is studied. It is found that with photochemistry and radiative transfer disturbances ...

Location and selection of an oviposition site is an essential part of the life history of all mosquito species. The remarkable number of oviposition be­ haviors range from the common, e.g. deposition of eggs on or near the water surface, to the unusual, e.g. egg brooding by adult females (73, 74). The initiation of an ovipositional flight is linked with environmental factors, especially rainfal...

The concept of marginalization, which is central to studies in political ecology, can be strengthened by incorporating a focus on the mutually constitutive concept of facilitation. Facilitation connotes how privileged groups are provided institutional forms of security in their pursuit of private gain, contributing to deleterious social and ecological outcomes. This paper builds on the concept ...

with the increasing population and the need for more food, as well as with the development of science and technology, human approach to unnatural and often chemical inputs to increase agricultural production has been a great expansion and problems such as increased cancers, chronic diseases has created environmental pollution. implementation of organic organic is a solution to these problems . ...

Weathering is a complex process comprising physical disaggregation, chemical and biological decomposition of rocks and minerals transforming complex structure minerals in simpler ones. Hydrolysis of silicates is perhaps the most important process but associated certainly to biological weathering. It is discussed the role ofwaters: activities/concentrations of chemical species, pH, Eh, importanc...
